Question on: JAMB Mathematics - 1992
find then equation line through (5, 7) parallel to the line 7x + 5y = 12
A
5x + 7y = 120
B
7x + 5y = 70
C
x + y = 7
D
15x + 17y = 90
Ask EduPadi AI for a detailed answer
Correct Option: B
Equation (5, 7) parallel to the line 7x + 5y = 12
5Y = -7x + 12
y = (\frac{-7x}{5}) + (\frac{12}{5})
Gradient = (\frac{-7}{5})
∴ Required equation = (\frac{y - 7}{x - 5}) = (\frac{-7}{5}) i.e. 5y - 35 = -7x + 35
5y + 7x = 70
